Mexican Shrimp and Octopus Soup with Pasilla

A robust Mexican seafood broth combining tender octopus and shrimp with roasted pasilla peppers, root vegetables, and tomatoes. The soup is built in stages: octopus simmers first to tenderize, vegetables char slightly in oil to deepen flavor, then everything melds together. Traditionally served in bowls with crusty bread, this is comfort food for family gatherings or when you want something warming and substantial. The pasilla peppers provide subtle smokiness without heat, while the seafood shells add natural depth to the broth.

Tips

Tip 1

To soften octopus faster, freeze it overnight before cooking; this breaks down muscle fibers and reduces boiling time.

Tip 2

Char the pasilla peppers lightly in the skillet before crushing them to intensify their smoky depth.

Tip 3

Leave shrimp shells on during cooking for richer broth flavor; guests can peel them at the table.

Good to Know

Storage

Cover and refrigerate up to 3 days. Octopus and shrimp may toughen if frozen; best eaten fresh.

Make Ahead

Prepare vegetables and crush pasilla peppers up to 1 day ahead. Cook the soup within 2 hours of serving for best texture.

Serve With

Ladle into bowls and serve hot with lime wedges, cilantro, diced avocado, and crusty bread on the side.

Common Mistakes

Watch

Do not skip the initial 20-minute octopus boil to avoid tough, chewy meat.

Watch

Do not fully cook vegetables in the skillet to preserve their texture when they simmer in broth.

Watch

Do not overcook shrimp after adding to the pot to avoid rubbery texture; 5 minutes initial boil plus 15-minute simmer is sufficient.

FAQ

Can I use frozen octopus?

Yes. Thaw it completely and reduce the initial boiling time to 15-18 minutes since freezing softens the tissue. Frozen shrimp should also be thawed before adding.

What if I cannot find pasilla peppers?

Ancho peppers offer similar mild smokiness, or substitute with 1 tablespoon smoked paprika mixed with 1 tablespoon tomato paste for depth without heat.

How long can I keep leftovers?

Store covered in the refrigerator for up to 3 days. Texture of seafood degrades beyond that. Freeze only the broth separately if storing longer.
